The title is more complicated than it has to be, here\'s the problem query.

SELECT * 
FROM query.multi 
WHERE queries=\"
    SELECT * 
        FROM html

    I've come up with a solution that doesn't really answer my original question but does solve the problem.

    The data.html.cssselect table will take a CSS selector & parse it into an XPath, avoiding the nasty escaping issues.

    SELECT *
    FROM query.multi 
        WHERE queries="
            SELECT * 
                FROM data.html.cssselect 
                WHERE url='http://www.stumbleupon.com/url/http://www.guildwars2.com' 
                AND css='li.listLi div.views a span';
            SELECT * 
                FROM xml 
                WHERE url='http://services.digg.com/1.0/endpoint?method=story.getAll&link=http://www.guildwars2.com';
            SELECT * 
                FROM json 
                WHERE url='http://api.tweetmeme.com/url_info.json?url=http://www.guildwars2.com';
            SELECT * 
                FROM xml 
                WHERE url='http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.guildwars2.com';
            SELECT * 
                FROM json 
                WHERE url='http://www.reddit.com/button_info.json?url=http://www.guildwars2.com'"
